Well I bought one thinking this is great for only $149. No! its worked for about 8 mins and stoped, motor will hum and then pop my 20 amp braker. looked inside and the fan move`s freely. Called Harbor Fright up and I am going to exchange it , but if any problems ill get my money back. The reviews where good I hope it was only a bad one,”ill see”. Also I bought a new sanding belt 6/48 that I need to return, crack along seem. it`s only a 35 min drive.
